MBeans search demo
Use MBeans to evaluate performance for the search demo.
Procedure
-
Change to the
demosdirectory.The default location of the demos directory depends on the type of installation:
-
Package installations:
/usr/share/dse/demos -
Tarball installations:
INSTALL_DIRECTORY/demos
-
-
Make
demos/solr_stressyour current directory. -
Create the schema:
pushd resources/schema && ./create-schema.shThe following options are available:
-
CQL table creation options:
-
--ssluse SSL for table creation over cqlsh
-
-
Solr HTTP options:
-
-e CA_CERT_FILE: use HTTPS with the provided CA certificate -
-E CLIENT_CERT_FILE: use the provided client certificate -
-h HOST: hostname or IP for Solr HTTP requests -
-a: Enable Kerberos -
-u USERNAME: Kerberos username -
-p PASSWORD: Kerberos password
-
The script creates the schema and posts the
solrconfig.xmlandschema.xmlfiles tohttp://localhost:8983/solr/resource/demo.solr/solrconfig.xmlandhttp://localhost:8983/solr/resource/demo.solr/schema.xml.The script then creates the search index by posting to
http://localhost:8983/solr/admin/cores?action=CREATE&name=demo.solr.You can override the script defaults by specifying command line parameters:
-x schemafile.xml -t tableCreationFile.cql -r solrCofgFile.xml -k solrCore -
-
Run the benchmark:
./run-benchmark.sh [--clients=CLIENTS_COUNT] [--loops=LOOPS_COUNT] [--fetch=FETCH_SIZE] [--solrCore=SOLR_CORE] [--testData=TEST_DATA_FILE] [--url=URL1,URL2,URL3...] [--qps=QPS] [--stats=true|false] [--seed=SEED_VALUE]The following options are available:
-
--clients: The number of client threads to create. Default:1 -
--loops: The number of times the commands list gets executed if running sequentially or the number of commands to run if running randomly. Default:1 -
--fetch: Fetch size for CQL pagination (disabled by default). Only the first page is retrieved. -
--solrCore: Search index name to run the benchmark against. -
--testData: Name of the file that contains the test data. -
--seed: Value to set the random generator seed to. -
--qps: Maximum number of queries per second allowed. -
--stats: Specifies whether to gather statics during runtime and create a csv file with the recorded values. Default:false -
--url: A comma delimited list of servers to run the benchmark against. For example:--url=http://localhost:8983,http://192.168.10.45:8983,http://192.168.10.46:8983. Default:http://localhost:8983
The demo creates a Search index named demo.solr and indexes 50,000 documents.
+ Example CQL commands:
+
./run-benchmark.sh --url=http://localhost:8983 --testData=resources/testCqlQuery.txt --solrCore=demo.solr+
./run-benchmark.sh --url=http://localhost:8983 --testData=resources/testCqlWrite.txt --solrCore=demo.solr+ See
/demos/solr_stress/README.txtfor execution modes and sample script commands. -

In JConsole, expand com.datastax.bdp > search > demo.solr to view the MBeans.
The CommitMetrics and QueryMetrics MBeans are present.
